1786-BNC

The trunk cable (catalog number 1786-RG6) is a low-loss, RG-6 quad-shield coaxial cable. It’s the bus or central part of the coax media system. The trunk cable is composed of multiple sections of cable. You can use several types of special-use cables, such as flexible (1786-RG6F), direct burial, or plenum rated, that are available from third-party vendors. Choose the cable type based on the application and or environment where your system is being installed. A cable connector (catalog number 1786-BNC) attaches coax trunk-cable sections to a tap’s BNC connector. Standard BNC connectors twist and lock onto the cable. However, these connectors are not designed for rugged conditions, such as vibration, water, and so forth. Use IP67 media connectors (catalog number 1786-TNC) that have screw threads for harsh environmental conditions.

A 75 Ω terminating resistor must be installed on the tap at each end of a trunk-cable section. Terminating resistors absorb the electrical energy of the signal at the ends of the cable to prevent reflections, which interfere with signals that are being sent. Two types of terminating resistors are available depending on the connectors and taps that are being used on a trunk line. There is a BNC terminating resistor (catalog number 1786-XT) and a TNC terminating resistor (catalog number 1786-TNCLXT4).
